Strangeness plus-one ($S=+1$) resonance-state $P_0^{+\ast }$ via $K^{+}n\to K^{\ast 0}p$

Dayoung Lee, Seung-il Nam

In our current study, we delve into the peak-like structure observed during the reaction process of $K^{+}n\to K^{0}p$ at approximately $\sqrt{s}\sim 2.5$ GeV. Our focus centers on ex…
